Well... writing to disk sure can't, but I guess there are image compression algos that can utilize multicores? After all, formats as png and jpg as far as I know, correct me if I'm wrong, tile the image and work on the tiles first. so if one would allocate a target memory area in RAM first and then fill the mem map with the to-be-saved data one could open a file handle right from the start and copy the mem portions to disk as they get filled by the compression algo. Or another approach would be make a copy of the image in RAM and do the save in the background. That way when using the same file name one would even narrow the state transition of the file to a minumum. Just an idea. -- -----BEGIN GEEK CODE BLOCK----- Version: 3.12 GCS d--(+)@ s-:+ a C++++ UL++ P+>++ L+++>++++ E-- W++ N o?
